What is the purpose of the ordering service in Hyperledger Fabric model?

Show Suggested Answer Hide Answer
Suggested Answer: D

In Hyperledger Fabric, if a user submits a transaction with no matching function specified in the smart contract, the unknownTransaction function is invoked by default. This function serves as a catch-all method that can be used to handle cases where the transaction type is not recognized, providing a mechanism to manage or log these occurrences effectively .

I think the ordering service is responsible for the overall ordering and consensus of the transactions in the network. It's not about endorsing or validating transactions directly, so I'll rule out options A and D. I'll go with C as the best answer.

Haha, yeah, the ordering service is the bouncer of the Hyperledger Fabric party. It's gotta let the right transactions in and keep the troublemakers out. I'd say C is the winner here.
